Suggest Treatment For Tiredness, Anxiety, Lightheadedness, Mood Swings And Stress

i am 20 year old female. Always tired, lots of anxiety and stress. i feel lightheaded a lot too. I am extremely moody and sometimes have no filter and say things I shouldn t. I feel guilty later. I am always hungry too. I am a very busy college student and I play two varsity sports throughout the year. Is it possible I have a thyroid disorder??
